Hi there. as a newbie I figured out the basics of R but when it came to graphic output it was a bad surprise. All but the X11 device do not function properly. Most of them generate an empty file and pdf() produces non valid output (gs and acroread as well). Very annoying, because I have to write a report. I got the recent stable binary rpm (v1.6.2) from CRAN on a SuSE Linux 8.1. Any help? CU

Let'say we have a dataframe mydata with column v1. If mydata$v1 is passed to a function, is there way, then, to extract the name of the dataframe? What I now do is passing the name of the dataframe to the funcion, so passing two parameters. Maybe with mydata$v1 it is not possible, but with mydata['v1'] or mydata[,'v1'] it is?

Hello I am having problems indexing a subset dataframe, which was created as: > waspsNoGV<-subset(wasps,site!="GV") Fitting a linear model revealed some data points which had high leverage, so I attempted to redo the regression without these data points: >wasps.lm<-lm(r~Nt,data=waspsNoGV[-c(61,69,142),]) which resulted in a "subscript out of bounds" error. I'm

I have a dataframe zeespan. One of the columns has the name "customer". The data in the customer column is text. I would like to return a subset of the dataframe with all rows that DON'T begin with either "ibm" or "exxon", or "sears" in the customer column. I tried .... subset(zeespan, customer != c("ibm" | "exxon" |

Hi everyone, I've got a dataframe with columns of different types. A certain number of columns in the dataframe hold the results of a series of Likert-type items. I've got a function that will print a simple table of frequencies and I want to apply that function to those columns of the dataframe only. What's the best approach? -Tim -- Tim Wilson | Visit Sibley online: |

HI, I have a dataframe like this: name type A t1 B t2 C t1 D t1 E t3 F t2 how can I have a "sub dataframe" based with the column "type" like this: (for type = t1) name type A t1 C t1 D t1 (for type = t2) name type B t2 F t2 Thanks -- View this message

I want to subset the dataframe based on certain values in a row. for each row in my dataframe if ANY one value of a particular set of columns satisfies cond append a logical value true at the end of the row else append a false at the end of the row in the end I want to be able to subset the whole data based on the appended true or false value. I could literally code like this, but I think

I would like to use the "row number" information returned from performing a subset command on a dataframe. For example, I would like to automatically delete some rows from a dataframe if they match a criteria. Here is my example below. data(airquality) names(airquality) subset(airquality, airquality$Month == 6) Now how do I delete the row numbers returned automatically? I

Hello- Sorry, this is a bit of a noob question, but I can't seem to progress it any further. I have two dataframes which contain a series of strings which exactly match. The problem is one has more rows than the other (more cases have been added) and they have been sorted so that they are not in the same order. The smaller dataframe, though, contains in another column which has codes

row <- c("a","b","c","d","e","f","g") #rows from larger data frame row.1 <- c("a","b","c","g") #rows of smaller data frame because d, e, and f don't contain any of the species, but the zeros are important x <- data.frame(sp1=rnorm(4), sp2=rnorm(4), sp3=rnorm(4),

Given the following dataframe: A=1:10 B=(a-5)^2 DATAFRAME=data.frame(A,B) How can I sort DATAFRAME increasing (or decreasing, for that matter) by B without making reference to A, or any other column? I've read ?order and ?sort but cannot seem to figure this out. Thank you. Mark

Hi, I searched for this in the mailing list, but found no results. I have a large dataframe ( dim(mydata)= 1297059 16, object.size(mydata= 145280576) ) , and I want to perform some calculations which can be done by a factor's levels, say, mydata$myfactor. So what I want is to split this dataframe into nlevels(mydata$myfactor) = 80 levels. But I must do this efficiently, that is, I

Dear R-experts Execuse me for an easy question, but I need help, sorry for that. >From days I have been working with a large dataset, where operations are needed within a component of dataset. Here is my question: I have big dataset where x1:.....x1000 or so. What I need to do is to work on 4 consequite variables to calculate a statistics and output. So far so good. There are more vector

Dear R-helpers, I have a dataframe called "trackpoints" with several columns including a column called "time", eg: > trackpoints ?? ? ? ?time 1 ? 12:00:00 2 ? 12:00:01 3 ? 12:00:02 . . . 298 12:04:57 299 12:04:58 300 12:04:59 I also have a dataframe called "data" that contains columns called "ID", "start" and "stop", eg: > data

Hi folks, I created a subset of a dataframe (i.e., selected only men): subdata <- subset(data,data$gender==1) After a residual diagnostic of a regression analysis, I detected three outliers: linmod <- lm(y ~ x, data=subdata) plot(linmod) Say, the cases 11,22, and 33 were outliers. Here comes the problem: When I want to exclude these three cases in a further regression analysis, - for

Hi I want to select a subset of a dataframe (frota) using the levels of a factor (matricula) in another dataframe (logbooks.eda).

Dear List, I'm stuck on what seems like a simple indexing problem, I'd be very grateful to anyone willing to help me out. I queried a dataframe which returns a character vector called "plot". I have another dataframe from which I want to subset or select only those rows that match "plot". I've tried subset, and also the "which" command. plot

Hi R helpers! I have the following dataframe ?choose? choose<-data.frame(firm=c(1,1,2,2,2,2,3,3,4,4,4,4,4,4), year=c(2000,2001,2000,2001,2002,2003,2000,2003,2001,2002,2003,2004,2005,2006),code=c(10,10,11,11,11,11,12,12,13,13,13,13,13,13)) choose I want to subset it to obtain another one with those observations for which there more than 2 observations in the column ?code?. So I want a

Dear R-helpers, for the purpose of plotting a dataframe, i am trying to sort a dataframe by one column, for example tester <- data.frame(one=c(3,2,1), two=c(2,3,1)) #> tester # one two #1 3 2 #2 2 3 #3 1 1 # I want to sort "tester" by column "one", so that i get a dataframe # that looks like: #one two #1 1 #2 3 #3 2 I know of 'sort' but
